50 Cent has upset the Doctor. In a series of tweets, the G-Unit rapper revealed that the super-producer is not happy with him after he decided to launch his own line of headphones.

The music mogul introduced his Sleek by 50 Cent wireless headphones last month, going up against Dre’s popular Beats by Dr. Dre. “Jimmy iovine and dre mad at me cause I’m doing sleek by 50,” he tweeted. “I guess I’m not going to be on detox Lol.”

He continued, “I’m a little hurt jimmy and dre feel like that but f*ck it. I’m focused I got a surprise for everybody this go round.”

The outspoken hip-hop star has supposedly addressed the situation in his music. “Would you faint if I told you I just wrote a verse about jimmy and dre. Oh my god this is hard. This shit gonna kill,” he said. “Em gonna have a heart attack when he hear this sh*t damn lol.”

50 was not pleased when Dre launched his headphones and didn’t include him and Eminem. “I don’t get it when they did there deal I didn’t get upset. Now I’m mad they didn’t put me or EM in that deal. F*ck this sh*t I QUIT,” he said before laughing it off. “Okok I’m done talkin bout jimmy n dre, I love them, they hate me, so what?…f*ck it. Lol.”
